Fluval FX4/FX5/FX6 Bio-Foam, Replacement Aquarium Filter Media, 2-Pack, A239

Exactly what I needed instead of going to the store.

These pads work great at catching all the super small things floating around in the tank and truly helping the water give that crystal clear look

Great replacement product

Perfect fit easy to clean.

Theyre ok, I guess. I noticed a SLIGHT improvement in my water clarity. I have 4 fancy goldfish in a 110 gallon and I feed Repashy Super Gold, so my tank is pretty messy. Im running an FX4 was unhappy with the clarity of my water. I put a fresh water polishing pad in the filter weekly and rinse out the old one to re-use. The pads are not very durable and Ill probably only get 2 uses out of them before they disintegrate. They are fairly inexpensive though, so I MIGHT buy them again...I dont know. I ended up adding a separate water polishing filter and some Purigen and my water is finally clear enough to satisfy me.

Items arrived on time, exactly as described.

Works like its suppose to

I use the Fluval FX5 filter for a 125 gallon RES turtle tank. For anyone out there that knows anything about turtles the are messy! With that said since I switched to the FX5 my tank has never been so clean and I dont have to clean the filter nearly as often as any other filter I have used on this tank in the past 4-5 years.

3 canisters 2 pads 3 boxes 2 months. you guys should allow more quantities for people with more canisters because i can only get 1 month of use out of the 3 boxes

This oem replacement works like it should by removing the finer particulates the larger pads dont. I added 2 of these polishing pads and a bag of carbon/ammo chips to the bottom basket of my FX6 and the water is sparkling clear on my planted aquarium. Once the pad starts to fall apart when cleaning, its time to replace. I recommend that these pads are replaced at that time and avoid trying to get more life out of it by placing it above the newer pad as some aquarium forum posts suggest as it may clog the newer pad as it falls apart.
